oknafyer reflashing the board with the latest build it fly now, not really sure what wrong before, the only thing i did was reflash and restore to defaults via cli, plugged everything back arm and it just works! time for some pid tuning

Zarkon - are those rctimer motors / props and prop adapters? If so I found the motors work ok but the collet type prop adapters they come with are quite low quality and tend to produce excessive vibrations. Also the rctimer plastic props are about the worse of the cheap props I've tried and wont be...

zarkon

dunno , setup looks legit. are you taking off in gyro-only? and all settings are at defaults (reset to defaults from console)? yes taking off gyro mode only, all setting are default out of the box only thing i changed is the min throttle for ESC init, i give another reset and give it another round ...

This is not something that would be broken by a firmware revision. well as for now i have no idea why it doing that, hand held test gyro correction are jumpy and sometime over correcting, would assuming updating the board wod restore it back to factory defaults and clear up the epprom no? my electr...

Hi all I recently replaced my GU344 from my DJI frame with Mini MWC 10DOF board, did a maiden flight a few minutes ago but I have some issues with the flight, it can flight but when hovering I notice the quad jerk/jump like is loosing power then back up again for split seconds, only noticeable when ...

it take me almost 2 day to finish reading all the post here

, finally I'm done looking forward to get GPS working on my IOI 10DOF mini wii board, I already order the i2c GPS from flytron looking forward on testing it

zarkon

When armed, all motors should run except if you checked MOTOR_STOP, is it the case ? nope I set my min throttle to 980 for esc on that video but later I changed it to 1120 as I always forgot if it is armed or disarm , I can't figure out the behavior need more test but I don't know where to start de...

Hi,

I recently bought one of those lite version, but at full throttle it just jumping and not flying. Throttle range are all set I even try to limit the range in multiwii config still the same, I have try 1.9,2.0pre1 and 2.0pre2 non of them works

Video

http://www.youtube.com/watch?feature=pl ... R1iFbNPrjQ

any idea what could be the cause ?

zarkon

Great, I quite surprise to see you use photoshop to make the shield as most ppl use eagle or something else

but the shield images are not the same as the actual picture, as the picture have 3 led your schematics only have 2

btw great job might try this later at home

this is a good opportunity for me to try vtail as I just crashed my quad few days ago the frame a busted, I didnt know this kind of thing is posible with multiwii Just one question thought does the new 1.9 support vtail by default? or some code change is needed for it to work? building is not a prob...

nice setup you have there I have one Tri base on rcexplorer too but using KK board still rebuilding My MWC missing some header pin stopping my build

zarkon

Here is some explanations: the HK 6 channel receiver is a cheap remote from hobbyking.com, complete set is about 40$ (remote and receiver). BUT: the newer versions do not have a PPM-sum signal (older versions did aparently on the battery connector pin). OK, so what you can do is to use up one pin o...

D/R and expo is also programmed on this switch.
Check Expo/DR tab in editor
Default settings is 0,100,100,0

I should have checked before asking, I saw your mix setup on ch6

I'm bit new to expo so not sure I know what all those mean

zarkon

does the eeprom posted earlier does it have the switch configuration for mode selection? can't figure out how to configure it on er9x

zarkon

If anyone is interested, I have a nice solution to the HK 6Channel receivers that do not have the sum signal (originally developed for the V1 of the receiver, but works also on V2 models). It uses 4 pins on the arduino, 3 to set a multiplexer (CD4051) and one for the multiplexed sum signal. I have ...

Finally around month of silence due to switching to KK board I'm back with MultiWii but this time I will be using this: http://iteadstudio.com/store/images/produce/Platform/ArduinoCom/Iteaduino2/iteaduinov2.0_3.jpg m It basiclly a adrduino uno clone but it have both 5v & 3.3v voltage by a flick ...

Glad to hear you sorted it. I'm sure I read somewhere of someone having a problem with their arduino not working on one pin for the motors and they used another pin but selected a different setup in the sketch.

still havent get this mini to fly with new shield + frame the same thing happen the rear right motor seem does not giving any lift causing the quad to flip over when throttle is given, I have no idea why now I'm stuck

Hi, Just to summarize what I did to get it working. Not a big deal but others may just find it usefull. I bought this blue-tooth module (Link http://cgi.benl.ebay.be/ws/eBayISAPI.dll?ViewItem&item=280611558914&ssPageName=STRK:MEWNX:IT )with on-board 3.3V regulator, the board connects direct...

I just got the mircro frame from BlueSkyRC will be re-building this mini quad hopefully with success

If you have no props then that will explain 0 gyro data, you must have got your gyro well insulated from vibration. balanced my prop seem to be fine now but it either keep flipping to right or left mostly to left w/o any reason m now my motor randomly shutdown while there is a gyro correction, the ...

zarkon

Vibration with a prop means you need to balance that prop. Have you set your esc max and min throttle commands again. Why is there no gyro data reading in the GUI, if you have vibration it will show in the GUI as the Gyros will be getting a shaking, you have a straight line, everybody dreams of hav...

zarkon

it seem that my right motor is shaking too much and cause vibration which effecting the throttle if, I guess the frame need to be redesign but still the right motor from the GUI show at full throttle it go up to 1850 (max throttle) but others wont g beyond 1750 any ideas why? this is after the acro ...

zarkon

The ESC controling the rear right motor is connected to pin 9 of the arduino, it must rotate clockwise with a clockwise prop. On the vid, your p is OK on the rear right motor b motor is spinning the wrong way. Swap 2 of 3 wires that comes from the ESC and go the to motor, you'll then be able to mak...

zarkon

well im sure the motor is spining the correct way but i'll double check again

zarkon

actually the prop is swaped but I fixed it the result still the same, I have being busy all days don't have time to test it, I'll make a new video when i have the time to test it again.

zarkon

Absolutely, I mean checking each "power unit" independantly in order to determine if it's the CPU board that does not allow the motor to pull up to full throttle. Check that in two steps: -> first directly from your receiver to the ESC witn a linear throttle curve and check if the thrust ...

zarkon

You could try to connect only one motor and its ESC at a time, and try to handle it by hand (be careful !), push the throttle until you feel a good lift from this motor side. Do this one by one for the 4 motor and ESC, I think you have contradictions in the corrections in the vid. I can do that but...

zarkon

no the bowl is just a stand it not attached to the quad
